novel means for causing the same to illuminate the surrounding area atpredetermined intervals. 7

A further object of the invention is to provide a movable hoodassociated with the burner for covering the burner to eliminate anypossibility of the light rays being projected therefrom.

A still further object of the invention is the provision oi a combinedhood and re hector, whereby the lamp may be supported in a convenientlocation as from the ceiling of a poultryvhouse, the combined hood andreflector acting to reflect the light rays downwardly. I

'W'ith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination and,arrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be 1nade within thescope ofwhat 1s claimed, without departing from thespi-ritof theinvention.

Referring to the drawings Figure 1 illustrates aside elevational view ofa lamp constructed in accordance with the present invention, thecombined hood and reflector being shown in section while the base of thelamp is partly broken away;

Figure 2 illustrates a -lr'ragmental sectional view through thebodyportion of the lamp, showing the spring controlled actuating means;

Figure 3 illustrates a sectional view taken on line 33 of Figure l;

Figure 4 illustrates a sectional view showing the controlling pinion assecured to the operating rod;

Figure 5 illustrates a sectional view taken on line 55 of Figure 4-.

Referring to the drawings in detail, the lamp includes an upper portionincluding a -ombined hood and reflector, thev same being llustrated bythe reference character 5, and as shown, the concaved surface thereof iscovered with a suitable reflecting material to cause thelight rays fromthe lamp, to be hereinafter more fully described and which is supportedunderthe concaved surface, to

be reflected downwardly. v

Tl'he member 5 1s preferably circular in.

plan and is provided with a central upwardly extending circular flange6, that is apertured at predetermined intervals to pro vide' aventilator for the hood, and at the same time provide means forconnecting the supporting hook 7 to the hood.

, The lower section of the lamp includes a casing 8 in which issupported the operating mechanism of the lamp, the casing acting as asupport for the oil tank 9 which has the burner 10 supported at "theupper end thereof, 'theburner being 01" the usual construction and pr 7vided with a wick and operating means.

Surrounding the tank 9 is a tubular guard 11'formedpreferably ofasbestos, the guard being of a length equal to the combined length ofthetank and burner, there being provided lugs 12 on the guard 11,adjacent to thebottom thereof, whichlugs have connection with theoperating rod 13, the rod 13 at one side 01": the guard 11 beingthreaded to operate through the pinion 14, while the rod 15 sets as aguiding rod to insure the contacts with the reflecting surface of theSE. (TU.O11"5"Wll1Ch bends the light rays downwurdly to illuminate thesu rounding area,'

The upper and lower sectionsof the lamp are connected by means or therods 17-and by means of which thellower section is' supported in properrelation with the upper section or hood 5. The operating means which issupported Within the casing 8 is of the spring motor control type, andcomprises a main shaft 18 which supports the sleeve 18 that is revolvedby the main spring 19, the sleeve 18 having a pinion 20 on one endthereof, that meshes with the pinion 21 carried by the shaft 22 whichhas one end there of supported by the bracket 28, and the op posits endsupported by the bracket 24.

On one end of the shaft 22 is mounted a disii to w ich is eccentricallyconnected the arm 26 that has its lower extremity connected to the.lever 27 which in -turn is connected to the lever 28, there beingrovided a slot in the lever 27 to accommo ate' a pin carried by thelever 28, to permit ofmbmmtof theilever 28 with respect to the lever 27.a

The levers 27 and 28hav'e pivot'a-lconnectipn with onewallof the casing8 and the a er-42s has ivotal connection with the sleev 29 thatlismounted to reciprocate on Shaft 18' the ends thereof cooperating theheveledpinions 30 and 31, which are inoved in one dircctionby means ofthe oiieaspring 32 associated therewith.

A spring member 33 connects the levers readilj under the influence ofthe main ,sprin 19. Mounted within the casing is shaft 34 which has athreaded portion podperating with the threads of thepinion 14, wherebymovement of the shaft 34 reattain a relative movement of the pinion Mwhich in turn imparts a vertical move- :ment to (the controlling rodlI-lto move the 'Ias will cause ,the threaded rod 13' to move the i1 guard11 longitudinally of the burner.

,Siipported on the shaft 3t is tLdISk 35 i whichmoveslongitudinally ofthe shaft by 30 I means 7,-. w

means ofthe overnor 36 and governor hich wei hts expand the "springs,under the centri ugal forceof the shaft to a pointwhere the disk 35contacts wifihthe feet 38 of the controlling member,

wit being understood that the shaft 34 re- ;jceives its owenf ron thepunch 39 carried one end thereof, and which is automaticall "Y thrown"into mesh with one of lathe piamnsao and 3laccord1ng to thed rectlondowniwardl bringing with it the tubular eard 11; obvious that asthe disk25 1S rotated the lovers 27 and 28 are noved ,to a position as indicatedin dotted 111168 in 27 and 28 to cause the levers to move morereflecting surface, a casing supported 1% Figure 2 whereupon the upperend of the sleeve 29 moves out of contact with the pinion 30 andthecoiled spring 32 at the upper end thereof forces the pinion 30 intoinesh with the pinion 39, whereupon the pinion 39 is rotated in theopposite direction to move the threaded rod 13 in the op ositedirection.

Vhen the sleeve 29 is moved downwardly, the lower extremity thereofengages the pinion 31 and moves the same againsmthe tension of thespring 32 thus disen ing' the pinions 31 and 39 leavin gaig the 1 mm3Uat the upper endthereot ohro tate the pinion 39.
